Answer:

x = -9

Step-by-step explanation:

x - ( - 5 ) = - 4

Distribute the negative sign

x - ( - 5 ) = - 4

x + 5 = -4

Inverse operations;

x + 5 = -4

  -5     -5

x = -9

What should the next number be? 100 96 104 88 120 56
riadik2000 [5.3K]

100 ---> 96 is -4

96 ---> 104 is +8

104 ---> 88 is -16

88 ---> 120 is +32

120 ---> 56 is -64  

So first we go down by 4, then up by 8, then down 16, then up 32, then finally down 64.  

The pattern of numbers is: -4, +8, -16, +32, -64  

Notice it's the powers of 2:  

2^2 = 4

2^3 = 8

2^4 = 16

2^5 = 32

2^6 = 64

each term doubles. Also each term alternates in sign. One is positive, then the next is negative and so on.  

The last difference is -64, which doubles to -128. Change the sign to positive to get +128  

Add 128 to the last term of 56 to get

128+56 = 184  

Therefore, the final answer is 184

Can somebody please help me???
matrenka [14]

Answer: B

Step-by-step explanation:

Domain is x values

Range is y values

Domain you look from left to right. You can see it starts at -3, and it goes all the way to 2. NOT 4 BUT 2!! Since we are looking at the X.

Range.. WE ARE LOOKING AT THE LOWEST POINT!! LOWEST POINT FIRST!1 I cannot stress enough. The lowest y-value is -2, and it's maximum point is 4!

REMEMBER:

DOMAIN = X LEFT TO RIGHT

RANGE= Y LOWEST POINT TO HIGHEST

USPshnik [31]

Answer:

95%

Step-by-step explanation:

Total distance of trip = 980 miles

Miles covered when Amelia slept = 931 miles

what percentage of the total trip had they travelled when Amelia fell asleep?

Miles yet to be covered = 980 miles - 931 miles

= 49 miles

percentage of the total trip had they travelled when Amelia fell asleep = 931 / 980 × 100

= 0.95 * 100

= 95%
